Comparative Study of Bipolar Hemiarthroplasty and Second Generation Intramedullary Nailing on Treatment of Elderly Unstable Peritrochanteric Femoral Fractures: Ho Hyun Yun, Gil Yeong Ahn, Il Hyun Nam, Gi Hyuk Moon, Jae Wook Lee, Jae Cheol Kim; J Korean Fract Soc 2006;19(2):128-134. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.128

Abstract: PURPOSE
To evaluate and compare the clinical and radiological outcome of bipolar hemiarthroplasty and second generation intramedullary nailing for elderly unstable peritrochanteric femoral fracutre.
MATERIALS AND METHODS
From January 2000 to July 2004, 56 elderly unstable peritrochanteric fractures were treated with a bipolar hemiarthroplasty (34 cases) or a ITST intramedullary nailing (22 cases). The fractures were classified using the OTA/AO classification. The clinical results were evaluated by walking capability, hip joint pain, and thigh pain. The radiological results were evaluated on the basis of the radiographs at follow-up.
RESULTS
In bipolar hemiarthroplasty group, The mean operation time was 134 minute, the mean blood loss was 648 ml. In intramedullary nailing group, The mean operation time was 103 minute, the mean blood loss was 386 ml. There were no different walking ability between prefracture and postoperative state in 22 cases (65%) of bipolar hemiarthroplasty group, 18 cases (80%) of intramedullary nailing group respectively. There were 5 cases (14%) hip joint pain in bipolar hemiarthroplasty group and 4 cases (18%) thigh pain in ITST intramedullary nailing group postoperatively.
CONCLUSION
Comparing the operation time, blood loss, and walking ability, ITST intramedullary nailing group show superior clinical outcomes than bipolar hemiarthroplasty group. However, The effort for decreasing postoperative thigh pain might be required.

The Operative Treatment of Scapula Fracture: Joo Tae Park, Gil Yeong Ahn, Young Shik Shin, dong Keun Kim; J Korean Soc Fract 1998;11(1):41-46. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.41

Abstract PDF: Fractures of the scapula are rare and those were treated conservatively, in general. But, some instances, conservative care cases remain limitation of range of motion, long standing pain and insufficiency of the muscle power. The purpose of his study is to evaluate the clinical results of the operative treatment on the scapular fracture. From May 1989 to December 1994, we treated 17 scapular fractures by the open reduction and internal fixation. We were able to follow up 14 cases, of which 11 cases(79%) had complete functional recovery. The other 3 cases (21%) had varying degree of pain, loss of mobility and weakness. Overall, however, 13 cases (93%) patients had good to excellent results.

A Clinical Analysis of the Tibial Pilon Fractures with Open Reduction: Joo Tae Park, Gil Yeong Ahn, Young Shik Shin, Young Tae Lee; J Korean Soc Fract 1997;10(4):816-822. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.816

Abstract PDF

A Pilon fracture, which is defined as a comminuted intra-articular fracture of distal tibia, violates the articular region and the metaphysis with occasional extension into the diaphysis, and renders the bone difficult to restore to its anatomic shape. Now there is wide consensus that more aggressive surgical treatment is needed to fulfill better result in such complex fracture. The authors analized 22 cases of pilon fracture of distal tibia that treated by the prinicple of anatomical reduction, rigid internal fixation and early rehabilitation at the Department of Orthopaedic Surgery, Pohang St. Marys Hospital from March 1989 to October 1995. The average follow up period was 54 months(from 16 to 90 months). The results were as follows ; 1. We obtained bone union in all cases and average union period was 19 weeks(from 12 to 26 weeks). 2. The most frequent type of fractures was type III(12 cases . 55%) according to Ruedi and Allgower classification. 3. According to the clinical results that classified by the criteria of the Ovadia and Beals subjective evaluation classification, type I and II were excellent and good, and type III excellent in 5 cases, good in 4 cases, fair in 1 case and poor in 2 cases. 4. The most important variables that influenced in the clinical result were the type of fracture and severity of soft tisuue injury.

The Treatment of the Intra-articular Fracture of Distal Radius: Joo Tae Park, Gil Yeong Ahn, Il Hyun Nam, Gyun Hwan Kim; J Korean Soc Fract 1996;9(1):193-199. Published online January 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.1.193

Abstract PDF: Althougn not as common as the intra-articular fracture of distal radius, if present considerable challanges in management. Because the intra-articular fracture is frequently accompanied by comminution and intra-articular extension of fracture, it can produce rome disability of the wrist joint. Now there are wide consensus that more aggressive surgical treatments are needed in such complex fracture to fulfill the better results. So recently, anatomical reduction, rigid internal fixation and early rehabilitation was recommended. The authors analized sixteen causes of intra-articular fracture of distal radius that were treated with open reduction and internal fixation at the Department of Orthopedic Surgery of Pohang St, Marys Hospital from March,1990 to December,1993. The object of this study is to evaluated the correlation between the rigid internal fixation and early rehabilitation. The average follow up period was 18.3 months(from 14 to 21 month) The result were as follows, 1. Among 1st 2 weeks after operation, long arm cast was applied. During 2nd 2 weeks, monster cast was applied. At 4 weeks, we started R.O.M.exercise and additional night splint was applied during 4 weeks. 2. The radiological union was achieved at all cases and the average time of union was 9.5 months. 3. According the Cole and Obletz criteria, excellent were 11 cases, good 3 cases, fair 2 cases. 4. We obtained satisfactory result by rigid internal fixation and early rehabilitation.

The Treatment of the Supracondylar-Intercondylar Fracture of the Femur: Joo Tae Park, Gil Yeong Ahn, Il Hyun Nam, Jung Kyu Ji; J Korean Soc Fract 1995;8(1):31-38. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.31

Abstract PDF: Although not as common as femoral shaft fracture, supracondylar-intercondylar fracture of the femur present considerable challanges in management. Because supracondylar-intercondylar fracture is frequently accompanied by severe soft tissue damage, comminution and intraarticular extension of fracture, it can produce some disability of the knee joint, So recently, early anatomical reduction, rigid internal fixation and early rehabilitation was recommended. The authors analyzed twenty cases of supracondylar-intercondylar fracture that treated at the Department of Orthopaedic Surgery of Pohang Saint Marys hospital from March, 1990 to December, 1993. The object of this study is to evaluate the corelation between the rigid internal fixation and early rehabilitation, The average follow up period was 18.3 months(form 14 to 27 months,) The results were as follows; 1, Among the twenty cases, male was more common than female and the prevalent age was 4th decade(50%). 2. The most common cause of injury was trafnc accident in 15 cases(75%). 3. During 1st 3weeks after operation, we started active R.0.M. exercise by using Thomas splint with Pearson attatchment and long leg brace with ischial weight bearing was applied from 3months to 6months (averge 4.2 months). We permit partial bearing Sweets after operation, 4. According to Schatzker and Lambert criteria, excellent were 16 cases, good 3 cases, feir 1 case. 5. We obtained satisfactory by rigid internal fixation and early rehabilitation.
